NEW YORK, Nov 29 (Reuters) - U.S. stock index futures turned negative on Monday as worries lingered about Europe's ability to contain a credit crisis despite agreeing to bailout Ireland over the weekend.
The concerns took the euro to session lows against the U.S. dollar and outweighed upbeat sentiment after a strong start to the U.S. holiday shopping season.
S&P 500 futures dropped 2 points and were below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures lost 12 points and Nasdaq 100 futures dropped 8.5 points.
